Abstract

We previously presented an optical design of a wideband spectrometer for science observations using space-borne telescopes; a multichannel configuration was adopted to cover a wide wavelength region from visible to mid-infrared and using the optical designs of each channel as independent spectrometers was also possible. In this study, we report some progress on works for the optical design of a spectrometer for space-borne telescopes that uses spectral dispersers made of infrared transmitting glass. We consider that infrared transmitting glass is a promising material for space-borne and ground-based optics for astrophysics, planetary science, astrobiology, and other fields.
